It's using the gfortran to link and then explicitly adding -lgfortran (twice, of course); gfortran will do this automatically. Also, if a executable has a main method in C, then you'll be more successful linking the program with gcc instead of gfortran (if it has a main program in fortran, then use gfortran to link). It might be possible to go the other way, but I have never had success.</blockquote>
